"Arsenal’s a big club, but I think Barcelona’s a level above, because of the talent of the players there.

"That’s no disrespect to Arsenal, because they have talented players, but I think the Barcelona players are above. I saw a lot of people come and a lot of people go at Arsenal."

The Cameroon international believes he has settled in well at Camp Nou, making 14 appearances for the Spanish giants so far this season.

Song still has fond memories of his time at the Emirates Stadium, but admitted the lure of Barcelona was too good to refused.

"Everything’s going well at the moment as we have started the season well," he added.

"I had some great times at Arsenal but I think it was the moment for me to change, to see something else, given the fact I had the opportunity to come to Barcelona, one of the best teams in the world."
